E-Cad organizes microvillosity-like structures. (A and A′) RC from a control stage 8 fixed GC stained for E-Cad (green) and actin (red). Actin staining is displayed under two different brightness/contrast settings to illustrate properly both the faint actin-positive filaments all over the cortex (seen better in A′) and the intense actin signal at the periphery of RCs (seen better in A). (B) RCs from control and E-Cad shRNAGL00646 live stage 8 GCs expressing the PH::GFP probe. (C) Control and E-Cad shRNAGL00646 fixed stage 8 GCs stained for Actn (green) and the inner rim marker Hts-RC (red). (D) Control fixed stage 9 GC stained for β-Cat (red), P-Moesin (green), and Actn (blue). Adhesive clusters are more peripheral than the portion of P-Moesin/Actn+ PM surrounding the RCs.

The authors also note that on page 12720, right column, first paragraph, line 7, “the E-Cad+ clusters” should instead appear as “the E-Cad/β-Cat clusters”; on page 12721, right column, fourth full paragraph, line 4, “1:100; DSHB” should instead appear as “1:100: BD Biosciences”; and, in the same paragraph, line 5, “1:50; DSHB” should instead appear as “1:50; ab50599; AbCam.”

The authors also note that, in the Supporting Information, page 1, right column, first full paragraph, line 19, “E-Cad clusters” should instead appear as “E-Cad/β-Cat clusters”; on the same page, right column, second full paragraph, lines 2–3, “1:100; DSHB” should instead appear as “1:100; BD Biosciences”; and, in the same paragraph, line 4, “1:50; DSHB” should instead appear as “1:50; ab50599; AbCam.” The SI has been corrected online.

Researchers report biparental inheritance of mitochondrial DNA in 17 members of three unrelated multigeneration families, paving the way for insights into alternative mechanisms for the treatment of inherited mitochondrial diseases.

Researchers report a machine-learning approach to identify land plants at risk of extinction, suggesting that the approach can be used to guide policies aimed at allocating resources for biodiversity conservation.

A study explores how cats groom fur using fine structures called papillae on the surface of the tongue and presents a biologically inspired hairbrush to remove allergens from cat fur and apply medications on cat skin.
